#NATURE Briefing

‘A historic moment for biodiversity’ More than 190 countries have cemented a hard-fought deal to safeguard nature, known as the Kunming-Montreal Global Biodiversity Framework, during the COP15 international biodiversity summit. “It’s a historic moment for biodiversity,” says ecologist Kina Murphy. For the first time, the agreement sets quantitative biodiversity targets, including: Protect and restore 30% of the world’s land and seas globally by 2030 Reduce the extinction rate by tenfold for all species by 2050 Critics note that the deal lacks mandatory reporting requirements and fails to call out the most ecologically damaging industries, such as commercial fishing and agriculture. There was controversy as the gavel fell at the event in Canada, which was co-hosted by China (because it was originally scheduled to take place in Kunming in 2020). Negotiators from several African countries said that China’s presidency ran roughshod over their concerns that they need funding to preserve some of the planet’s most crucial biodiversity hotspots.

T. rex didn’t roar — it cooed

We’ll probably never know for sure whether dinosaurs cooed like doves or boomed like cassowaries, but one thing is clear: they almost certainly didn’t roar. Researchers have yet to find any fossilized evidence of sound-producing organs like those of modern birds or mammals, so Tyrannosaurus rex probably resorted to closed-mouth vocalization — low-frequency sounds that are made by inflating the throat. Computer simulations of a hadrosaur’s hollow head-crest showed that it could double as a resonating chamber, producing a sound that palaeontologist Tom Williamson called “otherworldly”.

The Birth of the Soviet Union and the Death of the Russian Revolution

By Jonathan Davis

One hundred years ago, at the end of December 1922, the Union of Soviet Socialist Republics (USSR) was born. Vladimir Lenin, the creator and first leader of the Soviet Union, had denounced Tsarist Russia for holding Russians and non-Russians in a “prison of nations.” His new Soviet Union would unite the exploited masses of the old Tsarist lands in a country that was “national in form, socialist in content.” The Russification of the Tsarist era was over, as was the Russian chauvinism that Lenin despised. However, as was so often the case in Soviet history, the reality of this new way of life didn't live up to the promises made by the Party bosses in Moscow.

#Fronteiras do Pensamento (Postado em nov. de 2022) Como reinventar a humanidade na era digital? Assistimos ontem, eu e minha irmã Dra. Maria Helena. Recomendamos! Não há dúvida de que estamos mudando enquanto seres humanos, cada vez mais integrados com tecnologias que determinam, em grande parte, o rumo de nossas vidas, constata o físico astrônomo brasileiro Marcelo Gleiser. Durante sua conferência, ele propõe responder como podemos reinventar a Humanidade na Era Digital. E reflete sobre essa integração humano-tecnológica de que fala: ela traz muitas promessas mas, também, muitas ameaças sociais, emocionais, e éticas. Portanto, como desenhar nosso futuro usufruindo dessas tecnologias, mas mantendo nossa humanidade, nossa independência intelectual, nossa possibilidade de escolher o rumo e o sentido de nossas vidas? E como essas transformações alteram e ameaçam nosso projeto de civilização? Esses são alguns dos temas que aborda na sua apresentação. Assista à sua conferência e, ao final, a conversa do físico com a plateia, mediada pelo professor Rualdo Menegat. #National Geographic Magazine - History How Christmas has evolved over centuries People around the world celebrate the birth of Jesus Christ on December 25.
